This is needed to be in agreement with spec requirements:
https://github.com/KhronosGroup/OpenGL-API/issues/46
Piers Daniell:
"We discussed this in the OpenGL/ES working group meeting
and agreed that eliminating unused elements from the interface
block array is not desirable. There is no statement in the spec
that this takes place and it would be highly implementation
dependent if it happens. If the application has an "interface"
in the shader they need to match up with the API it would be
quite confusing to have the binding point get compacted.
So the answer is no, the binding points aren't affected by
unused elements in the interface block array."
v2: - 'original_dim_size' field moved above to keep
the struct packed better on 64-bit
- added a comment for 'total_num_array_elements' field
- fixed a binding point calculations for SSBOs array of arrays
( Ian Romanick <ian.d.romanick@intel.com> )
- fixed binding point calculations for non-packed SSBOs
v3:
- rename 'total_num_array_elements' to 'aoa_size'
( Jason Ekstrand <jason@jlekstrand.net> )
- rename 'boffset' to 'binding_stride'
( Alejandro Piñeiro <apinheiro@igalia.com> )
